Low-temperature pipeline airtightness test

Thread Content

Excuse me, does anyone have the air-tightness testing and operating procedures for low-temperature pipelines? Those using liquid nitrogen will work as well.

Why aren’t there any senior engineers to take over? What should be paid attention to when starting up low-temperature pipelines? What is required for a pipeline to withstand liquid nitrogen at -169 degrees Celsius?

Although I work on things related to this every day. . . But I don’t know the operating procedures for liquid nitrogen at -196 degrees

Upstairs? No way! So how does your liquid nitrogen system operate?
